Kromschroder Gas filter 81941190

The Kromschroder gas filter, SKU 81941190, is designed for the purification of combustible gases and air. It has a nominal diameter of 50 mm and flanges to ISO 7005. The maximum operating pressure is 1 bar. It includes pressure test points at the inlet and outlet. Under normal conditions, the pressure drop across a clean filter element should not exceed 10 mbar. As contaminants accumulate during operation, the pressure drop increases; when it reaches 20 mbar, the filter element must be replaced.

Parts of this type are selected by matching the nominal diameter and flange standard to the existing piping. Ensure the maximum pressure rating of the filter is compatible with the system's operating pressure. The filter is installed between flanges, and the pressure test points allow for verification of pressure drop. Before ordering, confirm the flange dimensions and bolt pattern align with the mating flanges.

When filters of this kind become clogged, the pressure drop across the filter increases. If the pressure drop exceeds the recommended threshold, impurities may pass through, potentially causing malfunctions or damage to downstream equipment. Regular inspection of the pressure drop is necessary to determine when replacement is needed.
